Deco codegen (generate-blocks, generate-schema, generate-invoke) and Fresh-to-TanStack migration tooling

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The migration has a user-selected project target and dry-run support, so the source does not establish an unconsented install-hook attack. Its always-applied agent guidance and removal of a project agent instruction file leave a concrete, bounded configuration risk.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A user runs the `deco-migrate` command on a project without dry-run mode.

Impact

The migrated project's Cursor sessions receive publisher-authored guidance, and an existing source-tree agent instruction file may be removed.

Mechanism

Migration scaffolding writes the Cursor rule, and cleanup may delete `src/AGENTS.md`; the rule includes destructive recovery advice for failed migrations.

AI rationale

Evidence

scripts/migrate.tsscripts/migrate/phase-scaffold.tsscripts/migrate/phase-cleanup.tsscripts/migrate/templates/cursor-rules.ts.cursor/rules/migration-tooling-policy.mdcsrc/AGENTS.md

Decision evidence

public snapshot

AI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The `deco-migrate` bin is an explicit CLI entrypoint; package scripts contain only build, test, typecheck, and lint commands.
The migration takes a source directory from CLI arguments and runs scaffolding and cleanup as migration phases.
Scaffolding writes an always-applied Cursor rule into the migrated project.
The generated rule points to a canonical upstream policy and includes advice to erase the working tree after a failed migration.
Cleanup can delete `src/AGENTS.md` when the migration runs without dry-run mode.

Evidence against

The agent configuration changes are part of an explicitly invoked migration, and the cleanup code has a dry-run guard.
No install lifecycle hook is declared in the package manifest.
